Summary
AI-generated from the abstractSerotonin (5-HT) dysfunction is present in people who use MDMA, is linked to the amount of MDMA they have consumed, and is not explained by cannabis use. The deficit relates to total lifetime MDMA consumption rather than how often the drug is taken, which argues against the idea that users are self-medicating a pre-existing condition. The findings are consistent with MDMA consumption causing serotonin impairment in humans.

Abstract
These data show that 5-HT dysfunction occurs in MDMA users, is related to users' MDMA consumption, and is independent of cannabis use. The results do not suggest that self-medication explains this relationship, because the deficit was related to total MDMA consumption but not frequency of consumption. The results are thus consistent with the thesis that MDMA consumption causes 5-HT impairment in humans.
